Novaseal has been helping customers in Fareham, Southampton, Portsmouth, New Forest, Chichester, and Hampshire and West Sussex areas with their double glazing requirements for two decades. We have the knowledge and experience to make your home improvement project a success.

54,000 Frames and Counting

54,000 Frames and Counting

In the last two decades, we’ve produced 54,000 frames for our homeowner and trade customers. We’ve achieved this volume without compromising on quality and by continually investing in our equipment and our people.

Although we can work to scale, we take time to build relationships with our customers. We’re never too busy to talk, and the owner of our business is always accessible, often working our trade counter during busier times.


We Invest in Our People

We’re proud of the fact that people want to work here. Novaseal trains develops and rewards the people that help make it so successful, which is probably why the average employee has been part of our team for eight years.

By retaining our staff, we’re able to help our customers. The teams that work in our manufacturing facility, behind our trade counter, and elsewhere, have the knowledge and experience needed to make our business successful.
